To put it bluntly, the main structure of the artillery locator is a laser rangefinder. In later generations, you could buy a good quality one for a few hundred yuan.
However, the civilian ranging equipment of later generations has a relatively limited detection range and is greatly affected by the environment.
If you are willing to spend several thousand dollars to buy a telescope with a rangefinder, then this thing will basically meet the measurement requirements required by artillery in this era.
However, that thing only allows you to see the distance between you and the opponent, and it cannot provide relative coordinates. What artillery observers do every day is to measure the distance and angle between themselves and the target, and then determine the distance between themselves and the markers.
The distance and angle between the reference object and the own artillery position are then used to calculate the coordinate position of the target relative to the artillery position using geometry.
Then, just like what everyone has seen in the movie, he reported to the artillery through the radio: "05 to the right, high and low plus five, three rounds of four guns, one shot, fire!"
Then wait... there was a "boom" and missed. This is normal. This process is called test firing, because there will always be a slight deviation due to human observation and calculation, plus various influences in reality.
After seeing the impact point of the projectile, the artillery observer's experience was most challenged at this time.
You must calculate the data that the artillery should adjust quickly enough, the faster the better. The enemy is not stupid. He knows that you are testing fire, how can he stay there and wait for you to explode!
If you are slow in calculating at this time, then it is estimated that others have finished running before you have finished calculating, and the mission has failed. Especially when dealing with armored targets, no matter how poor the maneuverability of the tank is, how many kilometers can it run out in a few minutes?
One hundred meters is no problem.
As a result, it is difficult for the artillery shells to keep up with the pace of the tank. This is not because the artillery shells fly slowly, but because the artillery observers calculate slowly.
Therefore, tanks can be regarded as the king of land warfare, which greatly shakes the status of artillery as the god of war.
Our country is a country with a phobia of firepower. The army has been bombarded by other people's cannons for decades. Now that we have the conditions, the artillery doctrine is prevalent. This has resulted in the huge amount of artillery equipment in our country. But today's cannons,
It is extremely difficult to deal with armored targets.
This is why the leaders at the time were so enthusiastic about the plan proposed by Zhao Ye. If computer technology can be used to calculate the position instead of humans, this will greatly shorten the preparation time for artillery fire and improve the combat effectiveness of the artillery in disguise.
.
Although using cannons to attack tanks is a helpless move, if it can be done and the time of artillery aiming can be shortened infinitely, then there are still many benefits to using cannons against tanks.
No matter how thick the tank's armor is, it can't withstand large-caliber artillery shells. Even if it can't hit it, the shock wave can kill the tank crew within the killing range.
Zhao Ye gave this department a task to come up with a special band laser ranging equipment as soon as possible. Zhao Ye had already written the plan and threw it on the table as soon as it came. The remaining time was used for them to conduct experiments.
of.
This rangefinder is required to measure a distance of not less than ten kilometers, the size cannot be large, the power consumption cannot be large, and the accuracy requirement is that at ten kilometers, the error must not be greater than plus or minus five meters.
Zhao Ye has specifically learned that the general absolute damage radius of 100mm caliber artillery shells at this time is about ten meters. If the error is plus or minus five meters, at least it is within this absolute radius.
The people in the Optoelectronics Research Laboratory felt a little nervous when they saw this data request. The torture last time was still vivid in their minds, and now it was about to start again.
"Mr. Zhao, this is for development for that unit this time. Why are there such technical requirements?" Director Zhao, the chief researcher of the Optoelectronics Research Laboratory, looked at the technical parameter requirements in his hand and did not think for a moment what unit would use them.
I saw something like this, so I asked subconsciously.
"Haha, Director Zhao, you are really smart and confused for a while. If you think about it carefully, who would want to use this thing?" Zhao Ye said jokingly.
"Is it possible that it is used in civil construction? But they must not use a measurement range of less than ten kilometers! That is what surveyors use." Director Zhao said with certainty.
"Well, your guess is correct. They do need such equipment. Unfortunately, you guessed wrong."
"Oh! Ah? Wrong guess? Then who else can use it?"
"Artillery observer! That's it. I plan to develop a laser rangefinder for artillery observers. This rangefinder must have these functions. First, the measurement range must reach ten kilometers. You can see this. Second,
The range-finding machine must be equipped with a computing chip to be able to obtain the relative coordinates of the opponent immediately. Third, it must have an interactive function with the rear, and the measured data must be transmitted back to the computer at the artillery position through radio equipment."
"Ah! Is it for the military?" Director Zhao was surprised. In this era, being able to develop military products is a very honorable thing.
"Yeah, how are you? Are there any difficulties?" Zhao Ye asked with a smile.
"Please organize the superiors, we will complete the task on time!" Director Zhao promised with his chest raised and his head raised. However, after finishing speaking, he bent down again and said to Zhao Ye: "But if we want to complete the task on time, we still need to
Please help me. I don’t have a clue at the moment.”
"These are some of my ideas. Let's see if they can be realized." Zhao Ye threw the plan over without any nonsense. Zhao Ye was worried that these people would develop such a habit.
In the future, I will no longer be willing to engage in independent research and development.
However, this is not an issue that Zhao Ye needs to consider now. If he wants to develop a usable rangefinder in a short period of time, he can only develop by leaps and bounds like this.
A rangefinder can't be done with just a rangefinder laser. It also needs optical instruments. For this task, Zhao Ye contacted Guanghua Factory through the channels of the joint factory. They specialize in making optical components. The task was assigned to them
In the factory, Zhao Ye didn't pay too much attention anymore. There was something like a monocular telescope on the left and right, and the difficulty was not too great.
Regarding the design of special-purpose chips, this task has also been taken over by the Institute of Microelectronics. Professor Ci and his team are now overcoming their problems. Only the Institute of Microelectronics is considered a professional in this aspect. Furthermore, the chip’s
The technical difficulty is not high, and the overall technical requirements are similar to those of Shuguang-1. The only difference is that this time the remote transmission function is added.
However, this function is not a big burden for the design of the chip. What is really burdensome is the design of digital signal transmission equipment.
This thing is not easy to develop, and Zhao Ye's next focus will be on this.
In addition, there is a lot of work that needs to be done by Laboratory No. 8 and the joint factory, such as overall design, structural design, tooling design, optical processing, electronic processing, laser testing, line installation, power supply matching and a series of other tasks. Because
No domestic military industrial unit has manufactured similar military products, and there is no reference standard. It all depends on Zhao Ye and others' independent design and trial production.
However, the joint factory is now considered to have experience. After all, it is a unit that has produced photolithography machines. It has a certain foundation for these things.
The entire design and verification work was being carried out in an orderly manner. After Zhao Ye finished his work, all that was left was to keep an eye on the research and development progress of each team.
In order for this range-finding machine to play its maximum role, the positioning vehicle is also an important part of it. Otherwise, the combat effectiveness of the range-finding machine will not be even half as effective.
The principle of this positioning vehicle is actually similar to that of a GPS satellite, except that it must use higher power signals to ensure positioning tasks in various complex geographical environments.
But as a result, the battlefield survivability of this kind of vehicle will become very poor. As long as the enemy has radio positioning equipment, this vehicle will be as dazzling as a large searchlight in the dark night.
However, Zhao Ye has no good solution at present. The only thing he can think of at present is to increase the number of such vehicles, such as increasing the number of such vehicles in the directions where they are needed and at dangerous distances. Using rotational starting.
methods to make up for this shortcoming.
The core part of the positioning vehicle is the timing system. This is not a simple thing.
Although the principle is not complicated, the difficulty lies in accuracy. For example, the quartz crystal oscillator used by Zhao Ye and others on the Shuguang series of computers can work very well.
However, the crystal oscillator made of this material is greatly affected by the environment. The temperature of the air, the pressure of the environment, etc. may affect its clock frequency. This is not a big problem when used in computers, but if it is used in different
On the positioning car, this impact is obvious.
If the three vehicles providing positioning have different crystal oscillation frequencies, then the times they send will be inconsistent. Such a small error will have catastrophic consequences.
What is the transmission speed of electromagnetic waves? Don't say too much, the clock frequency is only one millisecond different, and the measurement error may be several kilometers. This loses the meaning of positioning.
At this time, Zhao Ye had to choose to take a shower again and wanted to know what kind of material was used on the bald eagle's GPS back then.
As time passed day by day, Zhao Ye began to face more and more problems.
Now they are working on too many projects at the same time, including missile-borne computers, artillery laser rangefinders, photolithography machines and other equipment required for a new generation of three-micron process technology, and a new generation of processors.
It's about design.
Not counting the establishment of the information and communication network, the biggest problem Zhao Ye faced here turned out to be the program-controlled switches!
You know, in this day and age, the country still uses simulated manual exchange equipment, which is to call another city or place.
For example, to make a call from Beijing to Shanghai, you need to first get through to the telephone exchange in Beijing, and then tell the other party that you want Shanghai. After you get through to Shanghai, you have to tell the other party which district you want, and then wait, and then go to Factory Street.
Then say the number.
In this mode, it is wishful thinking to want to network computers.
